The conventional electroplating device that can electroplate multi-disc battery sheet simultaneously applies same voltage to same batch battery sheet; As depicted in figs. 1 and 2; Conventional electroplating device comprises plating tank 1, electroplate liquid 2, battery sheet 3, silver anode 4, conductive roller 5, conveying roller 6 and additional power source 7, and said plating tank 1 is provided with electroplate liquid 2, and said battery sheet 3 is located in the plating tank 1 with silver anode 4 and is immersed in the electroplate liquid 2; Said silver anode 4 is located at the position corresponding with it of battery sheet 3 belows; Be provided with conductive roller 5 above the said battery sheet 3, be provided with conveying roller 6 below the battery sheet 3, be provided with additional power source 7 between said conductive roller 5 and the silver anode 4; But owing to electroplate the influence of fringing effect; As shown in Figure 3, the plating weightening finish meeting of battery sheet that is in marginal position is bigger than the weightening finish of the battery sheet in mid-way, and just there is certain fluctuation in the quality of product like this.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of solar battery sheet electroplating device that improves electroplating evenness to be provided, can controlling the equipment of each sheet battery sheet impressed voltage respectively; Lower the impressed voltage of edge battery sheet; Strengthen the impressed voltage of middle part battery sheet, reduce the influence of electroplating fringing effect to a certain extent, thereby obtain stable plating weightening finish; Reduce the variance at processing procedure reference mark, promoted quality product.
The technical scheme that the utility model adopts is: a kind of solar battery sheet electroplating device that improves electroplating evenness; Comprise plating tank, electroplate liquid, battery sheet, silver anode, conductive roller and conveying roller, said plating tank is provided with electroplate liquid, and said battery sheet and silver anode are located in the plating tank and are immersed in the electroplate liquid; Said silver anode is located at the position corresponding with it of battery sheet below; Be provided with conductive roller above the said battery sheet, be provided with conveying roller below the battery sheet, said battery sheet is n (n for >=3 natural number); Be provided with the 1st additional power source between conductive roller on the 1st battery sheet and the silver anode; Be provided with the 2nd additional power source between conductive roller on the 2nd battery sheet and the silver anode ..., be provided with the n additional power source between conductive roller on n battery sheet and the silver anode.
The utility model galvanized battery sheet simultaneously adds impressed voltage respectively; Each additional power source can be controlled the size of impressed voltage respectively; Suitably strengthen the impressed voltage of intermediate cell sheet; Or the impressed voltage of reduction edge battery sheet, the weightening finish of same batch battery sheet is reached unanimity, thereby reach more stable product quality.
Beneficial effect: the utility model is applicable to the electroplating device that can electroplate multi-disc battery sheet simultaneously; Same batch of galvanized battery sheet realized different voltages with different control; Improve the high-efficiency battery sheet in electroplating process because the plating that causes of fringing effect is increased weight uneven problem, and the utility model do not change galvanized processing procedure, reduced and electroplated the influence of fringing effect to processing procedure stability; Make that the plating weightening finish is more even, promoted the quality of product.
